| ufumbuzi wa equation | Thamani ya kutofautiana ambayo inafanya taarifa ya kweli wakati kubadilishwa katika equation |
Dhana muhimu
8.1 - Tatua Equations Kutumia Kuondoa na Kuongeza Mali ya Usawa
- Kuamua kama idadi ni suluhisho la equation.
- Badilisha idadi ya kutofautiana katika equation.
- Kurahisisha maneno pande zote mbili za equation.
- Kuamua kama equation kusababisha ni kweli. Ikiwa ni kweli, idadi ni suluhisho. Ikiwa si kweli, idadi sio suluhisho.
- Kutoa na Kuongeza Mali ya Usawa
- Kuondoa Mali ya Usawa: Kwa namba zote halisi a, b, na c, ikiwa = b basi a - c = b - c.
- Kuongezea Mali ya Usawa: Kwa namba zote halisi a, b, na c, ikiwa = b basi a + c = b + c.
- Tafsiri sentensi ya neno kwa equation ya algebraic.
- Pata neno “sawa”. Tafsiri kwa ishara sawa.
- Tafsiri maneno upande wa kushoto wa neno “sawa” katika maneno ya algebraic.
- Tafsiri maneno kwa haki ya neno “sawa” neno (s) katika kujieleza algebraic.
- Mkakati wa kutatua matatizo
- Soma tatizo. Hakikisha unaelewa maneno yote na mawazo.
- Tambua unachotafuta.
- Jina unachotafuta. Chagua variable kuwakilisha kiasi hicho.
- Tafsiri katika equation. Inaweza kuwa na manufaa kurejesha tatizo katika sentensi moja na taarifa zote muhimu. Kisha, tafsiri sentensi ya Kiingereza kwenye equation ya algebra.
- Kutatua equation kutumia mbinu nzuri algebra.
- Angalia jibu katika tatizo na uhakikishe kuwa ni busara.
- Jibu swali kwa sentensi kamili.
8.2 - Kutatua Equations Kutumia Idara na Kuzidisha Mali ya Usawa
- Idara na Kuzidisha Mali ya Usawa
- Idara ya Mali ya Usawa: Kwa namba zote halisi a, b, c, na c ∙ 0, ikiwa = b, basi\(\dfrac{a}{c} = \dfrac{b}{c}\).
- Kuzidisha Mali ya Usawa: Kwa namba zote halisi a, b, c, ikiwa = b, basi ac = bc.
8.3 - Tatua Ulinganisho na Vigezo na Vipindi vya Pande zote mbili
- Kutatua equation na vigezo na constants pande zote mbili
- Chagua upande mmoja kuwa upande wa kutofautiana na kisha mwingine utakuwa upande wa mara kwa mara.
- Kukusanya maneno ya kutofautiana kwa upande wa kutofautiana, kwa kutumia Mali ya Kuongeza au Kuondoa ya Usawa.
- Kukusanya constants kwa upande mwingine, kwa kutumia Kuongeza au Ondoa Mali ya Usawa.
- Fanya mgawo wa kutofautiana 1, ukitumia Mali ya Kuzidisha au Idara ya Usawa.
- Angalia suluhisho kwa kubadili equation ya awali.
- Mkakati mkuu wa kutatua equations linear
- Kurahisisha kila upande wa equation iwezekanavyo. Tumia Mali ya Kusambaza ili kuondoa mabano yoyote. Kuchanganya kama maneno.
- Kukusanya maneno yote variable kwa upande mmoja wa equation. Tumia Mali ya Kuongeza au Kuondoa ya Usawa.
- Kukusanya maneno yote ya mara kwa mara kwa upande wa pili wa equation. Tumia Mali ya Kuongeza au Kuondoa ya Usawa.
- Fanya mgawo wa muda wa kutofautiana kuwa sawa na 1. Tumia Mali ya Kuzidisha au Idara ya Usawa. Hali ya ufumbuzi wa equation.
- Angalia suluhisho. Badilisha suluhisho katika equation ya awali ili kuhakikisha matokeo ni taarifa ya kweli.
8.4 - Tatua equations na Fraction au Coefficients Decimal
- Tatua equations na coefficients sehemu kwa kusafisha sehemu ndogo.
- Kupata denominator angalau ya kawaida ya sehemu zote katika equation.
- Kuzidisha pande zote mbili za equation na LCD kwamba. Hii inafuta sehemu ndogo.
- Kutatua kutumia Mkakati Mkuu wa Kutatua Equations Linear.
